Integration guide

How WooCommerce and Sellsy work together

Why?

The WooCommerce + Sellsy V2 integration connects your online store with Sellsy so ecommerce orders can be turned into Sellsy invoices automatically. It helps WooCommerce remain the sales channel while Sellsy becomes the back-office system for invoices, customers, payment follow-up and accounting preparation.

Target

It is designed for ecommerce merchants, brands, retailers, finance teams and operations teams that want to reduce manual data entry between WooCommerce and Sellsy. Customer details, order lines, shipping fees, coupons, taxes and payment references can be reused from WooCommerce to create more complete Sellsy documents.

Benefits

The integration helps teams save time, reduce copy-paste errors, keep customer records cleaner, apply useful Smart Tags, and give finance or support teams better visibility on ecommerce sales inside Sellsy.

Data flows

What moves between the apps

Primary sync path

WooCommerce is the source of truth for online orders. Sellsy is the destination for invoicing, customer records, payment tracking and financial follow-up.

The available workflow imports eligible WooCommerce orders into Sellsy as invoices. It can match or create customers in Sellsy, add product lines, shipping fees, tax information, coupon context, payment references, Smart Tags and custom field information where configured.

The workflow runs every 15 minutes, checking the last 2 hours of WooCommerce orders. Manual import is also available for testing, historical backfills, corrections or support investigations.

Reliability

Monitoring, failure handling and manual replay

Synchron focuses on operational visibility after the sale: logs, error context, monitoring and replay where supported. Read about trust and reliability.

Failure handling

Configured transfers are monitored with workflow logs and error context so teams can see which record failed and why.
Failures commonly need the underlying issue corrected first, such as credentials, permissions, product matching, order state, carrier data or a marketplace API response.
Where the workflow supports it, corrected transfers can be replayed or manually re-run instead of starting the whole process from scratch.

Manual replay

Manual import is useful during onboarding, backfills, support checks and controlled reprocessing of specific records.
Replay still depends on correcting the underlying issue first, such as product matching, credentials, permissions or invalid source data.

Use cases

When to use this connector

Enable it when WooCommerce orders should automatically become Sellsy invoices.
Use it when Sellsy is your main system for invoicing, customer administration and accounting preparation.
Use it to avoid manually copying customer, order, tax, shipping, coupon and payment information from WooCommerce.
Use manual import to test the setup, backfill historical orders, reprocess a missed order or investigate a specific order.

FAQ

Common questions

How often are WooCommerce orders imported into Sellsy?

The workflow runs every 15 minutes and checks the last 2 hours of WooCommerce orders. Manual import is also available for testing, backfills or investigations.

Why was a WooCommerce order not imported?

Check whether the order has one of the configured WooCommerce statuses. By default, only processing and completed orders are eligible.

Can I test the workflow before going live?

Yes. Use manual import for one or more WooCommerce orders, keep automatic invoice validation disabled, and review the draft Sellsy invoices before enabling more automation.

What happens if the Sellsy customer cannot be found?

The workflow can use WooCommerce billing information to match or create the Sellsy customer, so the invoice can still be created with the right customer context.

Can Sellsy invoices be created as drafts first?

Yes. By default, invoices are not validated automatically, which allows the finance team to review them before validation.

Can the integration mark Sellsy invoices as paid?

Yes, but this is optional. Enable payment creation only when WooCommerce payment information should be reflected as a Sellsy payment record.

How do filters and options affect imports?

The order status filter decides which WooCommerce orders are eligible. Sellsy settings control invoice validation, payment creation, shipping address handling, Smart Tags, document ownership, tax treatment and rounding adjustments.
